The paper addresses the importance of activities carried out by organisations as part of the internal dimension of corporate social responsibility (CSR) to employees' perceptions of the attractiveness of their employer, that is, the internal dimension of the employer brand (EB). This theme addresses the research gap identified during the literature analysis on the rarely addressed internal dimensions of CSR and EB. This review article attempts to identify the benefits of having an internal image of a responsible employer emerging at the level of employee attitudes and behaviour and the organisation as a whole. The article uses the method of critical review and analysis of the literature concerning the topics of the internal dimension of corporate social responsibility and employer image. The study offers a systematic review of the concepts related to the effects of CSR and EB directed at the internal stakeholders of organisations.
